COIN-CONTROLLED APPARATUS FOR DELIVERY OF LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 781,828, dated February7, 1905.

Application filed May 24, 1904. Serial No. 209,471.

1'0 11.77 /I'/1.()HI it may concern:

Be it known that l, ERIK (loans Jaxsos, a subject of the King of Swedenand Norway, and a resident of Stockholm, Sweden, have invented new anduseful Improvements in Coin- Uontrolled Apparatus for Delivery ofLiquids, of which the following is a specification, reference being hadto the drawing accompanying and forming a part hereof.

The present invention relates to coin-controlled apparatus for deliveryof liquids.

The object of the invention is to make such apparatus simple inconstruction and reliable in working.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

ln the accompanying drawing I have shown an apparatus embodying myinvention.

The figure represents a vertical section of the said apparatus.

An apparatus according to this invention consists of four mainparts---viz., a valve-casing. one or more electromagnets working upon adouble valve, a measuring vessel, and an automatically-operatingcircuit-breaker. From the valve-casing 1 extend three pipes or the ilike 2, 3, and i, the first one, 2, leading to a liquid-holder, (notshown;) the second, 3,1eading to a measuring vessel 5, and the third, 4,forming an outlet or spout through which the liquid llows out from thesaid measuring ve sel 1n the said valve-casing is arranged a doublevalve 6, adapted to tighten in its lower end position against avalve-seat 7 and in its upper end position against a valve-seat 8, thusplacing the measuring vessel 5 in communication with the outlet 4: andthe pipe 2, respectively. To the said valve 6 is secured an armatureadapted to be attracted by an electromagnet 10 when the latter isenergized. To the measuring vessel 5 or at the cover 11 ot' the same, asshown in the drawing, is pivoted a two-armed lever 12, provided at theone end with an insulating-block 22, to which is fixed a contact-plate13, which in the position of the lever shown in the drawing is oppositeand near to a slot in the coin-channel 1+1 without touching the latter.The upper side of the other end of the said lever 12 bears against aball 15 or the like, shiftably attached to a rod 16, that reaches outthrough the cover 11 ot' the measuring vessel and is attached to a float17 within the measuring vessel. The electromagnet 10 is by a wire 18connected with the contact-plate 13 and by a wire 190011- nected withthe one pole of a suitable electric current source, such as a galvanicbattery, (not shown,) the other pole of which is connected by a wire 20with a metal frame 21, which contains the coin-channel 14, likewiseInadc of metal.

The above-described apparatus works as follows: 'hen a coin is droppeddown into the coin-channel, the same will establish an electricalconnection between the coin-channel 1i and tho contact-plate 13, wherebythe circuit of the electromagnet 10 will be closed and the valve 6lifted into its upper end position. The liquid will then flow throughthe pipe into the measuring vessel and reaching the float 17 lift thelatter, so as to release the lever 12, which on account of the weight ofits lower arm will turn so that the contactplate 13 is removed from thecoin-channel 1% and the coin drops down, thereby breaking the circuit ofthe electromagnet 10. The valve 6 will then drop into the position shownin the drawing, thereby interrupting the communication between the pipe3 and the measuring vessel, estaldishing communication between thelatter and the outlet *1, through which the liquid contained in themeasuring vessel flows out. Tlhrough its own weight the tloat then willsink into the position shown in the drawing, turning back the lever 12,so that the contact-plate 13, as before, is placed near the coin-channel14: without touching the same.

1 am aware that electromagnetically-operated coin-controlled apparatusfor liquids are known before; but in those apparatus common cocks havebeen used, the plugs of which have been provided with arms constitutingarmatures for the clectromagnets. Such arrangements sutt'er from thedisadvantage that the electromagnets must be of comparatively largedimensions on account of the extensive motion of the arms of the plugs.

Having now described my invention and in what manner the same may beperformed,

float, a contact-piece secured to the said lever, a metalliccoin-channel having a slot near which the said contact-piece is normallyheld, the said coin-channel and contact-piece being connected in circuitwith the said electromagnet and a source of electric current,substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
